   51 Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
   52 a general description of GPIO and interrupt bindings.
   53 
   54 Please refer to pinctrl-bindings.txt in this directory for details of the
   55 common pinctrl bindings used by client devices, including the meaning of the
   56 phrase "pin configuration node".
   57 
   58 The pin configuration nodes act as a container for an arbitrary number of
   59 subnodes. Each of these subnodes represents some desired configuration for a
   60 pin, a group, or a list of pins or groups. This configuration can include the
   61 mux function to select on those pin(s)/group(s), and various pin configuration
   62 parameters, such as pull-up, drive strength, etc.
   63 
   64 
   65 PIN CONFIGURATION NODES:
   66 
   67 The name of each subnode is not important; all subnodes should be enumerated
   68 and processed purely based on their content.
   69 
   70 Each subnode only affects those parameters that are explicitly listed. In
   71 other words, a subnode that lists a mux function but no pin configuration
   72 parameters implies no information about any pin configuration parameters.
   73 Similarly, a pin subnode that describes a pullup parameter implies no
   74 information about e.g. the mux function.
   75 
   76 
   77 The following generic properties as defined in pinctrl-bindings.txt are valid
   78 to specify in a pin configuration subnode:
   79 
   80 - pins:
   81         Usage: required
   82         Value type: <string-array>
   83         Definition: List of gpio pins affected by the properties specified in
   84                     this subnode.
   85

   93 
   94 - function:
   95         Usage: required
   96         Value type: <string>
